9 Claims.

The present invention relates to a registering device and more particularly to a registering device having a disappearing stop or guide element.

In connection with photography, stencilling, printing and various other similar fields of endeavor, it is desirable to be able to orientate a member relative to another member. In photography, for example, it is necessary to position properly the sensitive paper with reference to the negative, and in various printing and stencilling operations it is similarly necessary to properly position one element relative to another. For performing this positioning or orientation function, it is customary to provide apparatus embodying suitable positioning guide elements or stop members. It is furthermore desirable that at certain times during the use of such apparatus that the guide members or stop members are effectively retracted so as in effect to provide a disappearing guide element or stop member. Heretofore very complicated arrangements were required to provide these disappearing guide elements or fingers.

It is an object of the present invention to provide a new and improved registering device for the purpose set forth above.

. It is another object of the present invention to provide a registering device including a guide finger or stop member forming a part of a collapsible linkage mechanism whereby the guide finger can be effectively retracted at the appropriate time.

Still another object of the present invention is to provide a disappearing guide finger or registering device comprising a collapsible linkage mechanism formed from a plurality of interfitting members.

It is a further object of the present invention to provide a simple, compact, sturdy, disappear-- ing registering device which is simple to manufacture and which may readily be used in connection with any operation where disappearing guide fingers or stops are required.

Further objects and advantages of the present invention will become apparent as the following description proceeds and the features of novelty which characterize this invention will be pointed out with particularity in the claims annexed to and forming a part of this specification.

For a better understanding of the present invention, reference may be had to the accompanying drawings in which:

Fig. 1 is a perspective view of a printing frame embodying registering devices of the present invention with the printing frame shown in one predetermined position;

Fig. 2 is a portion of the device of Fig. 1 showing the printing frame in a different predetermined position;

Fig. 3 is an enlarged view of a portion of the printing frame of Fig. 2 showing an end View of the registering device of the present invention in its effectively retracted position;

Fig. 4 is an enlarged sectional view taken on line 44 of Fig. 1;

Fig. 5 is an enlarged sectional view taken on line 55 of Fig. 2;

Fig. 6 is a top View .of one devices of Fig. 4; and

Fig. 7 is an exploded perspective view of the registering device shown in the preceding figures.

It should be understood that the present invention is applicable to many different devices for many different purposes and in fact, may be used wherever a disappearing stop or guide member for orientating a work member such as a sheet .of paper or the like is required. In order to illustrate the present invention, however, there is shown in Fig. l of the drawings a printing frame with which registering devices of the present invention are employed and since the registering device of the present invention is peculiarly related in an operative manner to certain features of such a printing frame or apparatus, the present invention is also concerned with the combination of the registering device and the printing frame or like apparatus.

Referring now to the drawings, there is illustrated in Figs. 1 and 2 a base I!) which may be in the form of a sheet of wood, plastic, metal or any other suitable material. If desired, this material may be supported from a suitable frame generally indicated at II. It should be understood, however, that the base ll) may be complete in itself and comprise only a sheet of material such as wood or the like. The base 10 forms a support for a work member such as I2 which may comprise a sheet of sensitive paper if the printing frame is used in connection with photography or a sheet of material upon which printing, stencilling, or the like is to be performed if the frame is used in connection with some other process. In order that the work member l2 may be properly orientated on the base l0, there is provided, more or less adjacent the periphery of the base 10, a plurality of elongated slots l3. Some of these slots extend in from one edge of the rectangular base member while other of these elongated slots extend in from other edges of the base of the registering member l0. Adapted to be positioned in one or more of these elongated slots I3, are the registering devices of the present invention generally indicated at 14. Actually, three identical such registering devices I4 are shown in Fig. l. of the drawings, two of which are positioned in the elongated slots l3 extending in from one edge of the base l while the other registering device I4 is positioned in the elongated slot l3 extending in from another edge of the base It. It is apparent from an examination of Fig. 1 of the drawings that these three registering devices M are sufiicient to properly orientate the work member I2 in a predetermined position. This position may be varied by changing the position in the slots l3 of the registering devices I4 or by supplying registering devices M in diiferent slots iii. In any event, the base It) is so designed that. the. Work piece may be positioned in a large variety of positions merely by moving the registering de vices l4 in the particular slots in which they are positioned or by physically moving the. registering devices 14 from the slots in, which. they are positioned to entirely different slots.

In connectionwith photograp y. certain printing and stencilling processes and the like it. is. customary to employ a movable frame member such as iiwhich in Fig. 1 of the drawings is illustrated asbeing hinged or pivotally supported to the base member H). As illustrated. asuitable rod t6: attached to. the frame member. if; by any suitable means such, for example, as the-fas.- teningmeans indicated-at. Hi. The rod l6. has its ends journalled in suitable bearingmembers- H which. arefastenedto a pair of angle ironsupports l8, one of these supports-being fastened to either side. of thebase member Ill. These angle iron-supports. i8 areprovided withra plurality of openings. such asi9 wherebythe bearing members: ilmaybe moved to various positions there- .i

by effectively changmgthe position of the movable.- or pivotally mounted frame member t relative to thebase H);

In: connection. with such a printing device as 1stillustrated in Fig. lof, the. drawings, it is custernary torproyide. a, holding device for holding: 2

theframe $5 in a predetermined position relative to the base Ii Such a. holding device is gen erally'indicated at; 285 inFig. 1 of. the drawings;

and forms no part of the present invention. As

iihrstrated; this holding device is identical with the: holding: devicedisclosed. and claimed inv my copending application, Serial No. 605,889, filed. Jul 19, 1945 now matured into- Patent No; 2,461,440 dated. February 8,1949; This holding device is'cohstructed tohold. the. printing frame in the position shownin: Fig. I of the drawings in the event. that: the frame is moved. to that. position. At. the same: time the holding device is: arranged topermit the frame [5 to move-to. the position indicated in Fig. 2' of the drawings. mere.- 1yby applying a slight force in a downward direction to the frame [5. Since the holding device 21 forms no part of the present invention, no further discussion thereof is included herein.

The registering device 14 per semay'be formed entirely of metal stampings as will become apparent as the following description proceeds and as aconsequence thereof, is relatively inexpensive to manufacture; Referring now to Figs. 4' to 7" ofthe' drawings, the registering device 14' comprises a primary supporting orbase member 2-2 which initially comprises a rectangular sheet of suitable material such as sheet metal or the like which has intermediate portions 22aandZEb-bent at right angles with respect to the main portion thereof so as to provide a channel portion intermediate the two ends of the primary supporting member 22. The ends 220 and 22d are provided with suitable openings 23 for fastening the primary supporting or base member 22 to a suitabledevice such as the base ID of the printing frame. The central channel-shaped portion of the primary supporting member is adapted to extend into the elongated slot [3 and the end portions; 22c and 2211 are sufficiently wide-to extend across the elongated sl-ot so that the primary supporting member may readily be fastened to the base it] as by suitable screws 24 clearly shown in Fig. dofthe drawings. The primary supporting member 22 is further provided with an elongated slot 25 in the channel portion thereof, the purpose of which will become apparent from the following description. In order to strengthen the primary supporting or base member 22, it may be desirable to provide a channel member such as 2-1: which may be suitably-fastenedasby welding or theliketo-the member 22, The channel member. 25; is also provided with an elongated slot- 21. which should. register, with thesslot- 25 when themember 26 is fastened as-flby welding or the, like tothe member 22.

For the. p rpose of s pportingthe disappeab ing-z stop or guide finger, there'isprovided asecondary supportingmemberla also in the formoi a. channel and having a. dimension so as, to fit.

within the. channel definedintermediate the ends.

of the member 22. This secondary supporting member, 28., is adapted to beslidably. movable with. respect to the member 22..and is provided with a.

suitable openingin the base ofth channel mem-v her for accommodating. a stov bolt such asis indicatedat 30. The nut. 29. associated with. the. stovebol't st. permits the secondary support. or sliding. member 2.8. to. be fastened-to the member 22,, and to be held in aposi'tion relative thereto determined by the elongated slots Ziand zlptl'ius.v

permitting adjustment. of the disappearingregistering device relative to the elongatedslots [3; in the base ID of the printing device when the primary supporting member 22 is fastened to the base Ill.

Within the secondary. support 28 there is pivotally mounted; a disappearing positioning guide element; or stop element, 32. A suitable pin 33? associated with the element 32" has its ends extending into suitable openings 28a in the member 28 whereby the element 321s pivotally supported within the channel-shaped member 28; The disappearing positioning guide element 32 also has a U-shapedor channel-shaped configuration; A channel-shaped lever3'l is provided which has one end thereof pivotally connected as by means of a pin 34 with the secondary'supporting member 28. This lever 3 is dimensioned so as to fit into the channel-shaped? secondary" support 28. V

I In order to operate the guide element or finger- 32 there is provided an actuator or actuating lever 35 dimensioned so as to fit within the space defined by the channel-shaped lever 3| and the channel-shaped positioning guide element 32. One end of the actuator 35 is pivotally connected by means of a pin 38 with the guide element 32, the pin 36 extending throughcooperating openings 32a and 35a in theelement 32 and the lever 35 respectively. An intermediateportion of the actuator 35- is positioned within the channelshaped lever 3| and pivotally connected thereto by means of a pin 31" cooperating with openings 35b in the actuator 35. Suitable means not shown are provided to keep the pins 33, 34, 36 and 31 in position. A suitably coiled tension spring 38 interconnects the pivot member 33 and the pivot pin 31. The pivot pin 33 is so positioned relative to the pivot pin 36 that the tension spring 38 normally biases the actuator 35, the lever 3| and the guide element 32 to the position shown in Fig. 4 of the drawings. In this position, the stop or guide element 32 extends upwardly through the elongated slot I3 in the base so as to provide a surface against which the work member l2 may engage as is clearly shown in Fig. 4 of the drawings. The actuator 35 also extends at an angle upwardly through this slot and is positioned so as to be engaged by the printing frame [5.

As the printing frame is moved from the position shown in Fig. 1 of the drawings to the position shown in Fig. 2 of the drawings, it engages the actuating members 35 of the registering devices I4 so that the collapsible linkage mechanism comprising the elements 32 and the members 33' and 35 collapse to the position shown in Fig. 5 of the drawings where these members interfit by virtue of the channel-shaped elements so as to be nested together in a manner to be wholly enclosed Within the secondary supporting member 28. It is apparent that the guide or stop members 32 are efiectively retracted within the elongated slots l3 so as to not interfere with the printing operation. In general a suitable member will extend across the printing frame I5 and if the registering devices such as the guide elements 32 were not effectively retracted within the slots l3 of the base Ill they would interfere with the member supported by the frame l5 not shown in the drawings.

In view of the detailed description included above, the operation of the registering device of the present invention will be apparent and no further discussion will be included herewith. It will be apparent that a registering device in the form of a simple collapsible linkage is provided, all parts of which may be made from metal stampings whereby the manufacturing cost is very low. In addition, a very sturdy construction is provided which is foolproof in operation and should provide long years of service. By virtue of the actuators 35 being engaged by the printing frame [5, the associated guide fingers 32 are automatically moved out of their interfering positions so as to be effectively retracted within the elongated slots [3 in the base [0. By employing the channel-shaped members which are nested together when the positioning device assumes the position shown in Fig. 5 of the drawings, a very compact structure is obtained which takes up a minimum of space.

It will be understood that the registering device although it is peculiarly adapted for use with printing frames such as is disclosed in the drawings, may be equally applicable to many other structures where such positioning devices are desired.

While there has been shown and described a particular embodiment of the present invention, it is to be understood that the arrangement disclosed is merely illustrative of the invention. It will, of course, be apparent to those skilled in the art that changes and modifications may be made without departing from the present invention, and it is aimed in the appended claims to cover all such changes and modifications as ondary supporting member fall within the true spirit and scope of the present invention.
